sneer-METAL BED.

To all 'whom t may concern:

i Be it known that l, F RANK P. ll/VILLIAMS, a

citizen of the United States, residino at Detroit, in the county lof`Wayne and @tate of Michigan, have invented certain new and usefulimprovements in Sheet-Metal Beds,

l of which the following is a specification.

This invention relates to sheet metal beds,

and has for its object a bed constructed almostwholly of sheet metal andwhich locks together with simple sliding joints.

ln the drawings,- Fig; l is a side elevation of a bed.

Fig. 2 is aplan view of the same with a partof the header strip brokenaway. f

Fig. 3 is a vertical longitudinal section on the line 3-3 of Fig. 2.

, Fig. 4L is a vertical cross section on the line Fig. 5Y is a sectionon the line 5-5 of Fig. 4..

Fig. 7 is'an enlarged section on the line ,7--7, of Fig. 2,showing'howthe clip 2 fastens the header stripl tothe head ,orfootasection on the line 6-.6 of

The.headboard of the bed ismade up yof two head plates@ and b providedwith lock* seam folds at each outsidel edge in which vlocks, thefolded-over edges of the post'strips c, asis shown in Fig. 5. These headplates are turned over at the bottom, as shown in Fig. 3, to form`right-angular doubled-back folds,'the foldclclosing the opening thatwould otherwise bein the bottom of the head vboard, and the fold eforming a supporting strip for the front ends of the side rails. Theside rails are designated ,f and are formed of a'single strip of metalbent to form a closed channel with the upwardly-proj ecting fold orflange g and downwardly-projecting .fold or flange 7L, in the latter ofwhich the seam is made simply by folding one edge of the metal over theother. The ends of the side rails are provided with turned-out flangesa' adapted to be slid in between the vlocleseam fold of the post stripand the front plate of the headboard. The lower wall of thD channel ofthe side rail f will rest on the top of the folded-over strip c, therebylocating the side rails at the proper height. However, to prevent theload of the springs, mattress and occupants carrying the side railsdown'by bending over the folded-over strip c, the post strips areperforated, asis also Specification of Letters Patent.

the head plate and the end flange 'e' of the rail, so that a' bolt orother securing member j may be passed therethrough asV shown in Fig. 5,to prevent the load carrying the side rails down. p V

One or more cross members lo' mayv be bridged across from rail to railand have their projecting ends rest upon the upper wall of the channel`of'the side rails, as is shown in Fig. 4. These form a support for thesprings. These cross members are constructed very similarly to the siderails, being a closed channel with outwardlyeprojecting flanges or foldsand with flat end eX- icn.

tensions that permit the crossvmember to v rest upon the side rails.

It will be seen that the front and rear plates a and b of the head boardhave `their box-like folds and malte. a strong reinforcementfor the headboard at the top and at the same time give an ornamental'appearance.

These-header strips also hold in place theA vertical reinforcingchannels vo which comprise channel strips of metal folded into channelform with turned-in edges ,o at the opening of the channel and with yaturnedout lip g at the top which lits in between the box-like foldZandthe header strip/fn so as to securely anchor the reinforcing channels0in place.v There are, preferably, two of these reinforcingchannels usedin the construction shown. This prevents the head plates from bucklingin and reinforces the entire head construction. Y

The postv strip c continues down to the floor; and has locl-seainedthereinto below the head plates a channel fillet strip 7'. (see Fig. 6),which has turned-out folds to en* gage in the lock-seam folds of thepost strip. This Yprovides a strong, durable post.

The construction of the foot-board is'the same as the headboard ingeneral. However, the foot-boarddsnot as high and a modified form ofconstruction at the bottom of the foot-board is shown. In place of thefolded over strips CZ and e at the bottom of the foot-board, folded lipss and t are turned folds of the foot-board plates in the same way andhave the same character of boxlilre folds at the top of the foot-boardplate that receives the header strip w of the footboard with theturned-over edges y. Both the head and foot board head-er strips areheld in place by the locking strip 2 shown in Fig. 7. rflesse can befolded into the lockseam fold of the header strip and when the headerstrip can slip over the box-like fold of the head board or foot boardthe strip may be folded into the position shown in the dotted lines,

From the above description it will be apparent that this bed made,outside of the bolts for anchoring the side rails in place, entirely ofsheetimetal folded into lockseams which can slide together and be heldin place simply by friction. This forms a knock-down bed which can bemade by simple sheet metal stampings in large production, shipped in almoclr-down condition and assembled together by the r 'iailer or Atheuser. ThisY will effect a very unusual saving in bed constructions ofthis type. 'With the many improvements that have come into vogue in theway of painting sheet metal in imitation of the natural woods, thisbed'will make a very acceptable substitute for the more expensivewoodenbed.

1What l claim is:

- l. ln sheet metal furniture, a memberfor useA` as a head, foot-boardor similar'relation, comprising a pair ofparallel plates with turned-outlock-seam folds turned back to parallel the plates andeach other and apair of post strips comprising .channels having turned-in lock-seamfolds paralleling the side walls of the channel adapted to engage thelock-seam folds of the plates to lock the plates together and form thecomposite member. I Y y 2.- ln sheet metal furniture, a member for useas a head, foot-board or similar relation,

comprising a pair of parallel plates of sheet metal with loch-seam foldsat the ends and channel strips with lock-seam folds locking into thelock-seam folds of the plates to form the posts and hold the platestogether to form a composite member.

3. ln sheet metal furniture, a mem] er for use as a head, foot-board orsimilar relation, comprising a pair of sheet metal plates, channelstrips with lock-seam folds detachably loclring into the lock-seam foldsof the side edges of the sheet metal plates to form the posts and holdthe plates together to constitute the composite member, said channelswith the lock-seam folds continuing below the plates to form the lowerrun of the posts, and fillet channels locking into the said folds of thelower run of the posts to reinforce the same.
